i Figures .ing over use my absorbent roll on the lower posterior rightside of the mouth. He bends up a straight absorbent roll having any ofmy flexible structures Figures 1-8, shape Fig. 9. He pushes the prong J,Fig. 9, down between and alongside the teeth and cheeks, which bringsthe loo I, Fig. 9, over the occlusal surfaces of ldiie teeth, and bringssimultaneously the prong K, Fig. 9, alongside the lingual surfaces ofthe teeth The pressure of the cheeks will hold the whole cotton roll inposition.

For work upon the upper posterior teeth my absorbent roll is bent in thesame way, used in the same way, and has the same highly advantageousproperties.

Let us assume that the dentist wants to use my absorbent roll for workon the anterior teeth. He bends up a straight absorbent roll having anyof the structures `1-8 into the shape, Fig. 9. He pushes the prong K,Fig. 9, between and alongside the teeth and lips, which brings the loopI, Fig. 9, over the incisal edges of the teeth, and bringssimultaneously the prong face of the teeth and gums. The pressure of thelips will hold the whole absorbent roll in position.

There are quite many advantages derived from an absorbent roll of myinvention. The slipping about of absorbent rolls in the mouth is a factwell known amongst dentists and is very frequently a source of serioustrouble and consternation during a dental operative procedure. Veryoften an absorbent roll will slip unnoticed near a surface of a toothwhere a crown or inlay is being cemented and have some of its absorbentmaterial caught beneath the cemented crown or inlay, becomingpermanently fastened there with the setting of the cement to thedetriment of the patient and to the exasperation of the dentist. It isunderstood that the t of the best fitting crown or inlay is ruined bythe shreds of absorbent material thus caught, after the remainder of theabsorbent roll is torn away.

Wherever it is possible the dentist uses clamps to hold the absorbentrolls in place. But he cannot use a clamp where it is reuired to havethe atient close the mouth rom time to time uring the course of anoperation, viz., examining for articulation in the process of arestorative operation. To this my absorbent roll of flexible form isconsiderably of advantage. The dentlst can bend my absorbent roll to theshape Fig. 9 and with the loop I, Fig. 9, passing over an appropriatespace of a missing tooth or passthe space posteriorly of the last molarthe patient is able to close the mouth into the vwhich have to beadjusted J, Fig. 9alongside the lingual sur` ployed together withincassi and if anything happens, instead of pushing the absorbent rollinto a filling or capping area, as would ordinarily happen with theclosing of the mouth, my absorbent roll is pushed away from the fillingor capping area. The value of such a feature will be highly appreciatedby a dentist.

Dentists often resort to powdering with certain powder ordinaryabsorbent rolls to avoid its slipping about the area in which it isplaced. But this staying effect of the powder is very quickly lost bythe slippery mucousy saliva coming in contact with the absorbent roll.

To prevent absorbent rolls from slipping dentists are compelled whereverpossible to use a series of clamps, known as cotton roll clamps, and anumber of each kind have to be kept on hand, such as molar clamps, hicus id and anterior clamps. These clamps on the teeth by forceps, butare not very easily adjustable in most cases, and far from comfortableto the patient, very often slipping down the tooth into the patients gumwith consequent excruciating pain. Clamps will often slip by themselveson the smooth tooth surface into the patients gum, whereupon, thedentist must instantly stop his work, which work as every body knows apatient wants to be quickly through, and after reassuring the patientthat the clamp will not slip .any more, being that it was adjusted, onlyto find that the clamp soon slips again.

The clamps referred to are powerful spring-like affairs having a shapelike the Fig. 9 of the appended drawing. The material comprising theclamp is of such powerful sprnglike material and construction that itcan only be manipulated with stout forceps. This powerful spring effectis emtion of the clamp in order to grip the smooth surface of the tooth.It is practical to assume 'that the knifed edged grasping parts of theclamp, under the power ul pressure of the clamp, scratches and otherwiseharms the enamel of the tooth. y

The evils of clamp use have always been known amongst dentists andnumerous devices are marketed to obviate the use of clamps withabsorbent rolls when work on the lower jaw is perforined--for the upperjaw nothing but clamps being possible to use with present forms ofabsorbent rolls. These devices are' practically all alike in that theyhold the absorbent roll in position like one does by placing his indexand middle finger over the cotton rolls and the thumb of the same handbelow the patients jaw or beneath the patients chin. These devices,however, are very bulky and often interfere with the work of a dentist.Furthermore, these devices cannot be used, as stated, for work on theupper jaw. Consea lmife edged terminau quently the upper jaw is limitedto the use of clamps with the attending evils. Although limited for themost clamps for holdin absorbent rolls 1n position, as explaine thedentist very often finds that he cannot use even this unsatisfactorymeans of holdin absorbent rolls. The tooth may be too s ort, causing theclamp through its spring action, to Jump ol'ie the tooth. Or the toothma be peg shaped and the clasp wont hold, a so jumping in the mannerexplained. Such absorbent rolls as mine, which keep themselves inposition, serve in such cases very usefully. Thus with m absorbent rollrequirin no clamps or ot er retaining means the di culties described areall overcome to the gratification of the patient and the dentist. i

lThe loop I, Fig. 9, of the absorbent roll gives a greater amount ofabsorbent material than when buccal and lin ual ieces of absorbentmaterial are use Gnsequently tained.

rlhe Hexibility of the absorbent roll gives rise to other desirablefeatures besides those alluded to. My absorbent roll can be doubled up,as shown in Fig. 10, to the right of the line QQ which is advantageousin several ways. First, where it is desired to kee the absorbent roll infirmer position, by doubling the absorbent roll whereit abuts the cheeksor lips adds thickness with consequently greater crowding and stayingeffect to the part of the absorbent roll within its confining space,between the cheeks or lips and the gums, thus, keeping the facial aswell as the lin ual portions of my absorbent roll firmly xed inposition.` Secondly, doubling my absorbent roll naturally means moreabsorbative material and a longer absorption period for the absorbentroll.

While the doubling of my absorbent roll is a com aratively slmple thingbecause of its iexib e properties, it is an impossible thing to do withOrdinar absorbent rolls. Furthermore, with my a sorbent roll thedoubling can be done in any direction. Of course, my absorbent roll canbe tripled as well as doubled.

Some dentists prefer to tear their absorbent rolls with the fin ersinstead of cutting it with a scissors. ligor this reason I show part toa longer absorption periodl is obbmy flexible material also in sectionedoi form, viz, Figures 4, 5, and 6. And with the lines H, Fig. 7exteriorly of the absorbent roll to show about where the sectionsterminate. It is a simple matter to tear the absorbent roll by hand-thesectioned off pieces of flexible material permitting it. Where tubularmaterial is employed, like Figures 3, 4, and 6, said tubu ar materialcan be of easily tearable material or substance. Thus a small piece ofabsorbent material, Fig. 8, can be torn awa or cut away from a regularsized strip o absorbent material.

My absorbent roll can be used `with a saliva ejector in a novel way. Asaliva ejector like Fig. 12 can be ushed into the hollow of theabsorbent rol ,presenting an appearance Fig. 11, to draw oii salivaabsorbed by my novel absorbent roll. Such a saliva ejector will workespecially well when my absorbent roll is provided with a tubularstructure like Figures 3, 4, and 6 and thei yof a dental absorbent rolland said absorbent roll embodying a flexible wire to render saidabsorbent -roll shape retaining when bent. 4

4. An article of manufacture consisting of a dental absorbent roll andsaid absorbent roll embodying 'a flexible wire to render said absorbentroll partially rigid so as to maintain an angular shape when bent.

5. An article of manufacture consisting a dental absorbent roll and saidabsorbent roll being hollowed out interiorly and inside of which hollowis another hollowed out part.
